Matthew Kassawara 5ee72cfa36 [install] Fix various minor problems
Fix the following minor problems to reduce work after
stable/liberty branching:

1) RDO: Revert Python MySQL library from PyMySQL to MySQL-python
   due to lack of support for the former.
2) RDO: Explicitly install 'ebtables' and 'ipset' packages due
   to dependency problems.
3) General: Change numbered list to bulleted list for lists with
   only one item.
4) General: Restructure horizon content to match other services.
   More duplication of content, but sometimes RST conditionals
   are terrible and distro packages should use the same
   configuration files.
5) General: Restructure NoSQL content to match SQL content.
6) General: Improve clarity of NTP content.

Other nodes

Other nodes reference the controller node for clock synchronization. Perform these steps on all other nodes.

Install and configure components

  1. Install the packages:

    ubuntu or debian

    # apt-get install chrony

    rdo

    # yum install chrony

    obs

    On openSUSE:

    # zypper addrepo -f obs://network:time/openSUSE_13.2 network_time
    # zypper refresh
    # zypper install chrony

    On SLES:

    # zypper addrepo -f obs://network:time/SLE_12 network_time
    # zypper refresh
    # zypper install chrony

    Note

    The packages are signed by GPG key 17280DDF. You should verify the fingerprint of the imported GPG key before using it.

ubuntu or debian

  1. Edit the /etc/chrony/chrony.conf file and comment out or remove all but one server key. Change it to reference the controller node:

    server controller iburst
  2. Restart the NTP service:

    # service chrony restart

rdo or obs

  1. Edit the /etc/chrony.conf file and comment out or remove all but one server key. Change it to reference the controller node:

    server controller iburst
  2. Start the NTP service and configure it to start when the system boots:

    # systemctl enable chronyd.service
    # systemctl start chronyd.service
